Population density Flashcards
How does relief affect population density?
People prefer to live on flat, low lying areas because it is easier to build on.
Mountainous areas have low population densities because thin or no soils limit economic opportunities and they are usually isolated making them hard to access.
How does being by the coast affect population density?
Coastal areas allow trade to take place easily from ports located by the sea, so many people live nearby for jobs
How does rainfall affect population density?
Many people prefer to live in temperate climates where there is enough rainfall to provide water.
How does extreme temperatures affect population densities?
Few people tend to live in areas with extreme climates because areas like the Sahara Desert with very high temperatures and low rainfall make farming difficult.
How does permafrost accent population density?
Few people live in areas such as Arctic Canada as permafrost makes building houses and roads difficult as the ground is frozen for much of the year.
Why do rainforests have a low population density?
Rainforests have a low population density because the environment is inhospitable and humid and tropical diseases like Malaria spread easily.
Why does soil affect population density?
People prefer to live in areas with fertile soils so that crops can be grown to supply food.
Why don’t people live in hot desert areas? (soils)
Few people live in hot desert areas because soil dries out and turns to dust, making it difficult to grow crops/keep animals.
